You do not always need an immigration solicitor, particularly if your application is straightforward and you can follow the official guidance carefully. Legal advice may be valuable if your case involves a refusal, overstaying, criminal convictions, complex family circumstances, or questions about eligibility and evidence. A solicitor regulated by the SRA can assess your circumstances, explain the risks and help prepare an application, but cannot guarantee a decision. Check the latest requirements and forms on GOV.UK, and consider professional advice if you are unsure.
